RESUMO

A deep perspective on students’ misconceptions on stoichiometry and Mass Conservation Law is presented. An evaluation of chemical discourse through textbooks allows teachers to be aware of the meaning of “chemical reaction”, “reagents” and “products” when talking with students. In addition, an analysis of how the omission of historical and philosophical reflections may lead to students’ misconceptions is also presented.
